Abstract

'This investigation was canied out to survey mites collected from certain
regions of North Sinai Peninsula, Northwestern Coast and Siwa Oasis. Results
indicated that survey proved the occurrence of 48 species belonging to 31 genera and
19 families where gasmid mites ranked the first as it included the highest numbers (37
species) followed by actinedid mites (5 species), oribatid mites(5 species) and
acaridid mites(one species).
Concerning Leafaspis astronomicus (Koch) that was recorded from North
Cost region reared on Rhabdifis scanica Allgen and Meioidogyne incognifa (Kofoid 8.
White) Chitwood at 25°C, prey species affected duration. fecundity and feeding
capacity of this predator. Generally, R. scanica was more suitable prey for L.
astronomicus comparing with M. incognifa. However, female consumed an averaged
140.8 and 27'20 juveniles of M. incognifa during immature and adult stage,
respectively. Thus L. astronomicus can be considered as biological agent against M.
incognifa.
